Bug#718698: [os-prober] ReiserFS support
it depends.... what you mean as "supported" ?
I'm using currently ReiserFS for all partitions on my Debian machines.
I'm using the latest kernel available on testing branch and reiserFS works.
Maybe you mean that new bugs on ReiserFS will no longer fixed, it's ok,
but the kernel is continuing to recognize and mount a ReiserFS partition.
If in os-prober ReiserFS is no longer supported this breaks the
recognizing of OS for the grub bootloader (for example)
Correct me if I have wrong.
